Finish Thompson Premium Inhibitor Blending Instructions
Finish Thompson’s Premium Inhibitor is a fully formulated antifreeze inhibitor package designed to
restore critical corrosion protection agents to glycol recycled with BE Series distillation systems. When
properly inhibited, the recycled glycol meets and exceeds various performance specifications including
ASTM D-3306, D-4985, D-6210 and TMC RP-329.
This one part formula is easy to use and economical. Because it works on all engine types, it eliminates
the need to have more than one formula for automotive and heavy-duty engines. In addition, it can be
used on either ethylene or propylene glycol.
When used with diesel engines, no pre-charge dose of supplemental coolant additives is required
(normal SCA maintenance is required).
Blending Instructions:
Use only ethylene or propylene glycol recycled using the BE Series distillation process.
Glycol must be between 50º and 100º Fahrenheit (10º and 38º Celsius) to be properly inhibited.
Begin mixing the glycol and slowly pour 2 ½ fluid ounces of Finish Thompson Premium Inhibitor for
every gallon of concentrated glycol produced by the BE Series distillation system. Continue to mix for
approximately fifteen minutes to ensure complete blending.
If a 50/50 mixture of glycol and water is desired, add the appropriate amount of low mineral content or
distilled water until the freeze point is –34º F (-37ºC). Use a high quality device such as a refractometer
to verify freeze point.
Note: Glycol produced by the BE Series distillation process can contain 10-20% water, do not mix 50%
water with the distilled glycol.
Store Finish Thompson Premium Inhibitor above 40º Fahrenheit (5º Celsius)
Use part number J104016 to reorder additional five-gallon pails of inhibitor
